Sevilla have the chance to make history on Tuesday and hold a slight advantage following the first leg having drawn 1-1 in Russia. Alvaro Negredo put the Spanish side ahead before Mark Gonzalez's brilliant long-range strike drew CSKA level.
Jimenez said: "It could be one of the most important games of my life, but honestly, and this isn't a cliche, for me every game that my team plays is important.
"But clearly it's an historical moment. It's a very important game for the club, the team, the city, Andalusia and Spain. Right now we are representing in Europe Sevillian and Andalusian football.
"Therefore, ahead of such an important event we have to increase our efficiency to try and reach the quarter-finals and convert it into an historic fact for Sevilla and the whole city."
